Recovered space balloon camera reveals footage of fall

Have you ever unexpectedly found something you lost years ago?

That is just what has happened to a group of scientists.

Bryan Chan, Ved Chirayath, Ashish Goel, Tyler Reid and Paul Tarantino, from Stanford University in the US, sent a camera to the edge of space two years ago - but couldn't find it when it came back to earth.

Now they have been reunited with their tech and have posted a video of what it filmed online.
